STAR RATINGS All conventional sized radials for agricultural applications are marked with the star ratings. This specifies the maximum load rating for the designated inflation pressure.

SPEED SYMBOLS The speed symbol determines the maximum speed allowed for the rated loads of the tire. From the table above, A8 means the maximum speed allowed for the rated load of the tire is 40 km/h or 25 mph.
